Terminals and Pipeline Leak Location

Terminals and Pipeline Leak Location

Don't let a small leak become a big problem

Damaged pipes not only leak product but profits and productivity. That’s why we provide a comprehensive suite of accurate and reliable technologies and services that are designed to fit the needs and budget of your business, and are backed by the best experience and reputation in the industry.

The Tracer Tight® leak detection technology is available for a wide range of applications, including aboveground storage tanks (ASTs), underground storage tanks (USTs) and buried piping. The Tracer Tight technology is one of the most accurate and sensitive leak detection and location technologies available. This technology is capable of satisfying most state regulatory requirements, and can be used as a compliance, consent decree, due diligence, or pinpointing tool. It even exceeds U.S. EPA requirements for precision tightness testing for USTs. Leaks as small as 1 gallon per day (0.05 gph) can be detected without interruption or excavation. This method is third-party evaluated and is listed by the U.S. EPA National Work Group on Leak Detection Evaluations (NWGLDE).

We’ve also developed the SeeperTrace® pipeline leak location service for long-distance pipelines. This commercially available technology quickly and cost-effectively locates leaks in buried pipelines that carry liquids, gases or multi-phase products. A leak as small as 2.5 gallons per day can be detected without service interruption or excavation.

And finally, our HeliTec® helium leak detection service quickly locates leaks in buried pipelines as well as plant piping and systems. The method uses a helium tracer in a gas, usually with nitrogen as a carrier gas, and a sensitive helium detector. The normal fluid is removed from the line, the line is pressurized with the test gas, and then the helium detector is used to sense the presence of helium in the air above the line.

Pressure and Leak Testing

New piping and vessels often need their mechanical integrity proven prior to use. Existing vessels and piping can require a similar test as part of an asset integrity program or for re-rating at a higher pressure. We offer pneumatic testing with our nitrogen pumping services.

For existing piping and pipeline, we can also add a tracer to either nitrogen gas or water to quickly and accurately locate leaks with our SeeperTrace® leak detection service, allowing the leak to be repaired and the test completed without costly project delays.
